cfetoolgraph – create graphs from a cfetool database
Synopsis
cfetoolgraph name [–path|-p
Description
The cfetoolgraph command dumps graphs of averages for visual inspection of the normal state database. The files are in a format viewable by "gnuplot" or "xgmr" or other graphical plotting program.
The command generates three or four files in a subdirectory of the database directory with a name beginning with either "daily", "weekly" or "yearly", then "-", then either "snapshot" or the current time, if the -T option is used. The files are named "average", "stddev", and "graph". The "graph" file contains both the averages and standard deviations, useful for plotting with error bars.
If a histogram file is present, a fourth file named "distr" will also be created, plotting the distribution of fluctuations about the mean value.
If the -d, -w and -y options are all omitted, the default is to only graph the weekly database.
Options
- –path|-p directory name
- The directory in which the database specified by name can be found.
- –daily|-d
- Graph the daily averages database.
- –weekly|-w
- Graph the weekly averages database.
- –yearly|-y
- Graph the yearly averages database.
- –timestamps|-T
- Time-stamp the output filenames with the current time, in order to give a unique name.
- –resolution|-r
- Generate high resolution data (), instead of averaging data over periods of one hour to generate simpler and smoother graphs.
- –help|-h
- Prints a short help message and then exits.
Example
% cfetoolgraph temperature --path /my/path --resolution
Create graph files of the weekly database in high resolution in the "/my/path/temperature/weekly-snapshot" directory.
